@camp8615 As a test, can you try with Roku Media Player app? It will see Emby as a DLNA server. Browse to the same video this way and attempt to play. If it plays it with the same exact issue, which I suspect it will, this is a Roku firmware issue with 8.2.x on certain RokuTV models regarding bitrate of HEVC files. Unfortunately the only way to fix it is lower the bitrate in app to cause a transcode. With HEVC this comes with a heavy cost. I wish there was something we could do to work around this but this requires help from Roku with correcting their firmware. As a side note, depending on what container the item is in, with Roku you can use higher bitrate with MKV than you can with MP4. If the item is an MP4 with HEVC try a remux to MKV and see if it works.

I'll try the Roku media player and see what happens. I'm wondering what Plex does to allow this file to play through the Roku. This is the only 4K HEVC I have, so I can live with it. If I were to post a Plex log would that be of any help?
Plex is likely fully transcoding it. You can provide a log from them though if you want. Sure. We can do the same thing and transcode, but we always play directly if supported.
Press down on your Roku remote to open the video player OSD when that video is playing. Use the playback menu (3 sliders like a graphic equalizer) and choose the playback correction option. This will cause the video player to exit and restart with the next playback method. If it still has problems, use the playback correction button again. There are multiple playback methods it will use as you use that button multiple times. It should eventually resolve the problem using this option.

So i tried all that @speechles said to do and was not able to get the stream to work on Emby or Roku Media Player. I went back to Plex and using the official Plex Roku app was able to get a direct stream for the HEVC video with HDR to work and the only thing being transcoded is the AAC audio from 7.1 AAC to 5.1 AC3. I am now going to transcode the audio on my MKV file myself and take out the VOBSUB subtitle file then remux and try again on Emby see if it'll will work. I attached 2 photos showing how its working on Plex and the Plex trancoder log see if it helps the admin.

So here are my findings: I transcoded AAC 7.1 to AC3 5.1 and EAC3 5.1 due to my current system capabilities and everything worked perfect. I did another test where i remuxed the .mkv file to have only the HEVC 4k video file and the AAC 7.1 audio and the same thing happened as before "RGB Fuzz". So i determined the culprit to be the AAC audio. My guess is Roku really does not like that codec. Thanks again for the help. I'm glad i was able to find a solution because like i said before I'm really liking this software and this community.
